perhaps you will be willing to write an article that introduces your company :)
"Using only geometry and properties of limits, it can be shown that the derivative of sine is cosine and the derivative of cosine is negative sine. One can then use the theory of Taylor series to show that the following identities hold for all real numbers x:"
This statement is false. I show a proof for this that does not use geometry or properties of limits on the trig identity article. I am removing the word only. --[[User:Dissipate|Dissipate]] 06:11, 28 Jun 2004 (UTC)
